Hi.
I just want to verify that a behavior that I am seeing with the synchronization signal is the expected behavior. I could not find this documented, but it seems like the built-in state synchronization signal, as accessed from the GUI, flips from high to low or vice versa not only during state changes, but additionally at the end of a trial. In other words, in the transition from the last state of trial 1 to the first state of trial 2, I see 2 bit flips. Is this what is expected?
To give some background on my setup, I have synchronization configured via the GUI to flip BNC1 with every state change. I am recording this channel on a NI data acquisition system at around 10khz. In the transition between trials, I effectively see 2 bit flips-- one I presume is when a new trial is started, and the second I presume is when the first state of a new trial starts. The interval between these two bit flips (ie the duration of the 'new trial being summoned' state) is variable between 10 and 30 milliseconds, and doesnt seem to be obviously related to size of state matrix to load/send.
Thanks!
